OUTLEI NOZZLE FOR ATOMIZING AND SPRAYING LIQUID ANTISEPTICS UNDER PRESSURE.

Application filed April 17, 1920. Serial No, 374,689.

To all whom it may concern:

Be itknown that I, Lnwrs KEMPTON MOBLEY, a citizen of the United States, and resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Outlet Nozzles for Atomizing and Spraying Liquid Antiseptics Under Pressure, of which the following is a specification.

This invention relates to outlet nozzles for atomizing and spraying liquids under pressure, and it has for its object to provide a simple and improved nozzle of this class which will be particularly adapted to high pressures and will possess. advantages in point of positiveand eifective operation and general efliciency.

y present improved nozzle is particularly adapted to the conditions of operation and use as set forth in my co-pending applications for patent, Serial No. 311,947 for an improved method of applying liquid antiseptics, and Serial No. 313,371 for an improved means for applying liquid antiseptics, in which a liquid antiseptic is combined with carbonic acid gas in sufiicient volume to carbonate the antiseptic to the desired degree of pressure in a normally hermetically-sealed container, from which a volume of the carbonated antiseptic solution is discharged by valve control through an outlet tube and simultaneously with said discharge converted at the point of ejection into the outer air under action of the caris particularly adapted bonic acid gas into an antiseptic carbonated spray. While the improved nozzle as comprised in my present application for patent or effective service and facility of operation and general elli- "ciencyunder the conditions as 'ust set forth to convert a jet of carbonate liquid antiseptic ilnder high pressure into a whirling atomizedspray, it will be understood that the improved nozzle is not restricted to this condition of use and'that it may be empld ed in all conditions and circumstances view Fig. 3 isa detail cross-section, on an en:

' larged. scale, taken on the line 3-3, 1.

Fig. 4 is a detail cross-section, on an enlarged scale, taken on the line 4-4, Fig. 1.

Fig. 5 is a detail cross-section, on an enlanged scale, taken on the line 5-5, Fig. 1. orres onding parts in all the figures are denoted y the same reference characters.

Referring to the drawings, the body of the nozzle device is tubular and is preferably constructed in two sections, 1 and 2, respectively constituting an inlet member and an outlet or discharge member. The inlet' member 1 consists of a tube of desired length, having a longitudinal bore, 6, of relatively small or narrow diameter, and adapted to be secured in fixed connection to the outlet portion of a supply member or container from which the liquid under pressure is discharged into said tube, for which Y purpose the terminal connection end of the member 1 is preferably externally threaded, as at 7, for engagement with a threaded orifice in the supply member of container. The discharge member 2 of the nozzle consists of a tube of desired length, having a longitudinal bore, 8, of relatively large or increased diameter, and extending from the inlet memher 1, the connectiontherewith beingpreferabl by means of a threaded connection, as at 9, etween the rear end of the member 2 and the front end of the member 1, the construction being such that the end of the member 1 is received within the end of the bore of the member 2, whereby the tubular sections of the nozzle are separably connect-- ed and carried one upon the other. The bore of the outlet section 2=constitutes a terminal tube chamber which, as beforestated, is of anenlarged or increased diameter with relation to the diameter of the bore of the inlet section 1, and which is extended longi tudinally to afford a desired degree of, len h I'OVl es in-said terminal tube chamber and a cylindrical interior 'wall throng out the length thereof.

The tubular nozzle carries interiorly means for retardin the jet of liquid passmg under pressure om the bore of themlet section 1 andfor deflecting the jet and imparting to it a spiral whirlinganotion as it passes into and-through the enlarged terminal tube chamber of the'discharge section 2. Said conversion and deflecting and retarding means comprises a block-partitio 10, which is fixed the tubular body 0 the nozzle immediately in front of the bore of the inlet section 1, said block-partition sponds in. diameter thereto, and is in fixed. position against the end of the inlet section 1 which extends within said bore. I have herein shown one means of mounting the block-partition in its fixed'position, in which the circumference of the block is provided with external threads, asat 11, engaging with the terminal inner portion of the threads '9 within the bore 8 of the section 2 by which the sections 1 and 2 are secured together, but it will be understood that the blockartition may be mounted and secured in its ed position within the tubular body of the nozzle in any suitable or adapted manner.

The block-partition 10 has an internal spiral channel, 12, extending from a small inlet orifice, 14, at the center of the inlet face of the block member, to a small outlet orifice, 15, adjacent the periphery of the outlet face of the block member, said channel thus forming a gradually widening spiral from the centered inlet orifice 14 to the peripherally-located outlet orifice 15. .The outlet terminal end portion of said spiral channel, which forms the orifice or port 15, extends to the terminal orifice in a direction following the course of the spiral, as indicated in Fig. 4. The spiral channel is also preferably so provided 'or formed that the longitudinal extent of the gradually widening spiral is located in .the same plane transversely of the body of the nozzle.

In the practical construction of the blockpartition, to produce the conditions as above noted, the block body preferably consists of a main disc, 16, in the face of which is formed the spiral channel 12 and through which the outlet orifice 15 extends from the terminal end of said-channel, and a supplementary face plate or disc, 17, covering the channelledface of said body disc 16 and having a central orifice intersecting the initial terminal end of the spiral channel 12 and constituting the inlet orifice 14, said main body disc 16 and face disc 17 being permanently secured together by welding or in any other suitable manner. In the preferred relative construction, the diameter of the inlet orifice 14 in the face disc 17 preferably corres onds to the diameter of the small bore 6 of t e inlet member 1 of the body .of the nozzle, with which it registers.

At the terminal discharge end of the outlet section 2 of the body of the nozzle, the internal wall of the longitudinally-extended cylindrical tube chamber which is constituted by the bore8 is preferably contracted spirally-rotating jet will pass in a fine whirl- 'ing' atomized spray under pressure, and the outer end of said orifice 19 is preferably flared or cup-shaped, as'at 20, to enhance the spread of the spray,

The operation and advantages of the improved construction of nozzle as comprised in my invention will be readily understood. The pressure jet entering from the relativelysmall or narrow bore of the inlet section 1 to the inlet orifice 14 of the block-partition 10 is retarded within the block body by the spiral channel thereof and is deflected and converted by the gradually widening spiral into a spirally-rotating jet of high speed under pressure, which passes from the outlet orifice 15 adjacent the periphery of the conversion block into the chamber 8 formed by the bore of the discharge section 2, in

which it passes forwardly at high speed, in-

a. spiral whirling motion guided by the cylindrical interior wall of said chamber 8,

throughout the length thereof and to they to impart to the jet spiral whirling motion under which it is finally ejected in a fine whirling atomized spray, is enhanced by the gradually widening form of the spiral channel and its location with its longitudinal extent in the same plane trans versely of the nozzle, and by the relative size or diameter of the respective bores and the spiral channel, in which the terminal tube chamber 8 is of enlarged or increased diameter with relation to the inlet bore 6 of the section 1 and the spiral channel 12, to afiord a spread to the spiral whirling jet which issues from the conversion block under pressure, and by the extension of said terminal tube chamber 8 longitudinally to aiford 'a continued-length guidance to the s iral whirling action of the jet within said 0 amber'before it is finally ejected therefrom as a fine whirling spray. It willbe understood that the various parts are magnified in the accompanym -drawings, for purpose of illustration, an

that in practical construction for usual conditions of service and use the parts are of small or minute size, especially the bore 6' v according to desired conditions of se yice and use.

I do not desire to be understood as limit-- ing myself to the detail features of construcwidening spiral ,channel having its tudinal extent in, the same plane trans tion and arrangement as herein illustrated and described, as it is manifest that modifications and variations therein may be resorted to in the'adapta'tion of the construction to varying conditions of use, without departing from thespirit, and scope of my invention andimprovements. I therefore reserve the right to all such variations and modifications as properly fall within the scope of my invention-and the terms of the following claims.
